CHARLES CHISHOLM, OF NEW YORK, N. Y.

FOLDING STAND.

Application filed February 19, 1916.

To all whom it may concern Be it known that I, CHARLIcs CHIsHoLM, a citizen of the Dominion of Canada, and a resident of borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Folding Stands, of which the following is a specification.

My invention relates to folding stands and is adaptable to music stands, tables, sign stands, and various other uses.

My invention comprises improved means whereby the legs of such stands or tables, and the arms or brackets supporting table tops and the like, may be extended into working position, or, when desired, folded up alongside of the central post, and may be locked in either position.

The object of my invention is to provide improved and simplified locking means for stand legs, bracket arms, etc.

I will now proceed to describe my invention with reference to the accompanying drawings and will then point out the novel features in claims.

Figure 1 shows an elevation of a music stand embodying my invention. Fig. 2 shows an elevation of a table embodying my invention. Fig. 3 shows a horizontal section on the section line A-A of Figs. 1 and 2. Fig. 4 shows a horizontal section on the line BB of Figs. 1 and 2. Fig. 5 shows a side elevation of the connecting sleeve of the stand, and of a portion of the center post of that stand, the legs or bracket arms being omitted. Fig. 6 shows an axial section of the parts shown in Fig. 1, with one of the legs or brackets connected to such sleeve, such leg or bracket being also shown in dotted lines in its folded up position. Fig. 7

- is a detail perspective view of one section of the sleeve. Fig. 8 is a view similar to Fig. 6, but illustrating an alternative construction. Fig. 9 is a vertical section of a coat hanger or costumer embodying my invention. Fig. 10 is a fragmentary perspective elevation of one of the legs or arms of my device, Fig. 11 is a view similar to Fig. 6, but illustrating a further alternative construction.

In the drawings numeral 1 designates the sleeve, and numerals 2 designate arms, (specifically, legs) pivoted at 3 to the projecting ears 4 of the sleeve. .5 designates a center tube or post, shown in the drawings as holler {though t is Fe immater al) and go Specification of Letters Patent.

able vertically through a predetermined range, with reference to this sleeve. The ears 4: are preferably arranged in pairs as shown, each leg 2 being located between the ears of one such pair, and the sleeve 1 has an opening between the ears of each such pair, permitting the butt edge 6 of each leg 2 to engage the surface of the post 5 when that post is in its normal or elevated position. The post 5 is capable of being raised from the position shown in Fig. 6 to a position such that its lower end clears the butt ends of the legs, so permitting said legs to be swung up in the position indicated in dotted lines in Fig. 6, whereupon, the post. 5 being lowered again, its surface engages the secondary butt surfaces 7 of the legs so holding those legs in the raised or folded up position. In order that the post 5 may be held normally in looking position, the sleeve 1 is provided with an internal groove 8, the main portion of which is vertical, z'. 6., parallel to the axis of the sleeve, but provided at its lower end with a right angled portion 9; and a stud 10 screwed into the post 5 is arranged to travel in this groove.

It will be apparent that normally each leg 2 is held locked, either in its extended or in its folded up position, by engagement of either the surface 6 or the surface 7 of such leg, with the surface of the central post 5; but that by raising such post with reference to the sleeve the said legs are unlocked, and may be swung from the extended to the folded up position, or vice versa, and then may be locked in such new position by lowering the post 5 again; the locking being completed in each instance by turning the post with reference to the sleeve so that the stud 10 lies within the bayonet-joint extension 9 of the groove 8. This means for locking the parts in their extended or folded po sitionis not confined to the legs of stands and the like, but is equally applicable to table top supporting brackets, and the like, as indicated particularly in Fig. 2, wherein I have shown a tabletop 11 resting upon brackets 2 hinged to a sleeve 1 corresponding in all respects (except as to external form of the brackets 2 adapting them for their particular purpose) to the sleeve 1 and legs 2. In fact, the construction of the parts 1 and 2 is precisely the same as that of the parts 1 and 2, except that the parts 1 and 2 a e W Q w th r fe t P 1 and 2; and the brackets a may be unlocked by turning the sleeve 1 slightly and then raising it,with reference to the post 5; whereupon the brackets 2 (having first been disengaged from the table top 11 and that top removed) will swing down and may then be locked in such lowered position. An opening 12 is provided in the sleeve 1 (and a similar opening will be provided in the sleeve 1) whereby, in assembling or disassembling, the stud 10 maybe inserted or re moved.

Asindicated particularly in Fig. 8, the post 5 may have slots 18 corresponding to the slots 8 of sleeve 1, so that, to unlock the legs 2 or brackets 2*, only a slight longitudinal motion of the post 5 with reference to thesleeve 1 or l is required.

It will be obvious that the construction herein described is applicable to very many devices other than stands, tables, etc.; for

example, the projecting arms of coat hangers, hat hangers, and other devices of a similar nature, as for example, the well known device commonly called a costumer, may be arranged to be locked or unlocked as herein described. In Fig. 9 I have shown such a costumer, numerals 2 designating the arms or hooks thereof. In this Fig. 9-

construction the locking member is a bolt 5* fitting within the sleeve 1, this sleeve being carried by the post 14.

In the various constructions of my device herein illustrated and described, it is convenient to form the sleeve 1 of sections 1 such as shown in Fig. 7 these sections being riveted together as indicated.

As illustrated in Fig. 11 the central post 5 may have slots 14 which will be brought into registry with the edges of the arms 2 permit them to be moved from the one position to the other; and whenever-said arms are in either of their two extreme positions rotation'of th'e'post 5 so that said slots 14 are no longer opposite the butts of the arms 2, looks said arms. 1

As indicated particularly in Figs. 6 and 8, the ears & may be provided with stops 15 V adapted to engage notches 16 in the arms whereby said arms'are arrested. in proper position to be locked by the post 5.

What I claim is: I
